Trane Intellipaks

Have a site with a few Trane Intellipaks. They have BCI boards down to a Jace. The problem I'm having is space temperature.

I'm averaging the VAV's and writing to the BAS Space Temperature. The problem is, the units are using the local space temperature from the connected zone sensor.....for active space temperature. I tried changing the space temperature source at the RTU, but I still can't get the RTU to use the BAS input.

So I finally got back over there. Here's the scoop. By writing to the BAS space temperature, it doesn't change the active space temperature. But my MWU, DWU, and Unocc heat/cool is using my BAS space temperature for control. So I guess there wasn't any issue?

This sounds familiar. I ran into this issue a year ago with Intellipaks connected to my customer's JCI system by Lontalk cards. Trane guy got his support on the line and they said this is the way the Intellipak works. It only reports the communicated "BAS" space temperature as the active value when its actually being used. It only gets used during morning warm up, daytime warm up, unoccupied control and if you select zone based supply air temperature reset. Sounds like you have them all disable in the Intellipak unit interface screen.

I have DWU disabled and doing my discharge air reset outside the unit.
